PostgreSQL is an advanced Object-Relational database management system (DBMS).

A flaw in the LOAD command in PostgreSQL was discovered. A local user could use this flaw to load arbitrary shared libraries and therefore execute arbitrary code, gaining the privileges of the PostgreSQL server. The Common Vulnerabilities and Exposures project (cve.mitre.org) hasassigned the name CAN-2005-0227 to this issue.

Multiple buffer overflows were found in PL/PgSQL. A database user who has permissions to create plpgsql functions could trigger this flaw which could lead to arbitrary code execution, gaining the privileges of the PostgreSQL server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-0245 and CAN-2005-0247 to these issues.

Users of PostgreSQL are advised to update to these erratum packages which are not vulnerable to these issues.
